HINGE.

Specification of Letters Patent.

Patented Dec. 12, 1911.

Application filed September 1, 1911. Serial No. 647,231.

To all whom it may concern:

Be it known that I, Josnrn Soss, a citizen of the United States, and residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Hinges, of which the following is a specification, such as will enable those skilled. in the art to which it appertains to make and use the same.

This invention relates to hinges for doors,

and particularly to what are known as invisible hinges of the class described, and claimed inU. S. Letters Patent #825,943 granted'to me- July 17, 1906 and #880,697 granted to me March 3, 1908, and the invention described and claimed herein while being, in particular, an improvement on the construction described and claimed in the last of the above named patents, is designed to render hinges of this class more strong and durable and also more simple in construction and effective in operation, and one of the objects thereof/- is to provide a hinge of the class specified which in. addition to being used on doors, may also-be used on or in connection with gates, window sashes, piano-covers, wardrobes, closets and in various kinds and classes of cabinet work.

The invention is fully disclosed in. the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in tion of the construction of each of the views, and in which Figure 1 is a perspective view showing the separate parts of my improved hinge disconnested; Fig. 2 a sectional view showing a part of a door and a part of a door frame and showing the method of applyingmy improved hinge, the view of the hinge being a back view'thereof and the door'being in a closed position; Fig; 3 a View similar to Fig.

2, but showing, the .door swung through an arc of 180 degrees and showing part of the construction broken away; Fig. 4 a'sectioii on the line 44 of Fig. 3 and showingthe door closed,'in full lines, and in an open'position, in dotted lines; Fig. 5 a section on theiline 5-5 of Fig. '6, and; Fig. 6 a viewlooking in the direction of the arrow 6 of Fig. 5,. said Figs. 5 and-6 being a modificacertain parts shown in the other figures of the drawing.

In the practice of-rny invention as shown in Figs. 1 to 4, inclusive, I provide a hinge which involves two main similar parts or comprises a main plate'member a, said plate members a being adapted to be abuttcd as shown in Fig. 2, and to be secured in a door frame 7) and a door 6 by means of screws 6 and for this purpose the ends of the main plate members a'-- are provided with screw holes I). For the purpose of this description the abutting surfaces a of the main plate members if, when said plate membersare securedinposition, will be called the faces ofsaid plate members and the op osite surfaces a the backs thereof, and the backs of said plate members are provided centrally with oblong 'body portions 0 the corresponding sides of which are cut out transversely to form main recesses c which extend through the plate w members a and which form parallel top and bottom faces a in which are formed grooves c which range transversely of the plate members a through the body portions 0, but do not extend through the front faces'of the plate members at, and the back walls 0 of the irecesses 0 which extend; forwardly .to the faces a of the plate members a are provided with supplemental transverse recesses c which open forwardly through the plate members a and in planes at right angles to the planes of the grooves of, and the jaws formed by the recesses 0 are beveled or rounded outwardly as shown at c. I also provide oblong floating .link members 03, three of which are shown and .which are placed transversely in the recesses c as and which open backwardly shown in Figs. 2, 3 and 4, and which are provided with forwardly directed end projections d through which are passed pins d movable in the grooves 0* and provided with anti-friction rollers d. .I also provide attached and L-shaped link members e which are placed between the floating linkmembers d, and one end portion of these L-sllaped link members is pivoted in the recessesc by 'means of pins e p which pass entirely through the plate members a longitudinally thereof, and the other end portions of said L-sl1aped link members are pivoted between-and to the I floating linkmembers d by pins a and contrally of said link members a7.

With-this construction the door 6 may be swung through an arc of 180 degrees as shown in Figs. 3 and 4, and at the same time said door is swung clear of the frame 6, and while I have shown but three of the floating link members (5 and two pairs of L-shaped and attached link members 6, it will be understood that any desired number of these scribed. said link members may be clearly seen when the door is open. and in order to prevent this result the link members d may be integrally connected by a back plate f shown in Figs. 5 and 6 without in any way interfering withthe operation of the hinge as tr-whole, and the plate f will .conceal the link members 6 and also the link members (Z except at the extreme ends thereof.

My invention is not limited to the exact method herein shown and described of connecting the link members a with the link members (I, all that is necessary in this connection being that said link members 0 be pivotally connected with the link members (I centrally thereof so as to insure the operation of said parts as herein shown and described.

As shown, the ends of the main plate members'a and the ends of the back body portions (2 formed integrally therewith are rounded or made semicircular in form, the object of this being to facilitate the formation of the mortises in the door frame and door in which the separate hinge parts are secured The wort floating used herein as descriptive of the link members (Z is intended to convey the idea that said link members have no direct or positive connection with the main parts or leaves of the hinge, such as a pivotal or similar connection, but instead thereof have only a'sliding connection -with said main parts or leaves in addition to the connection formedby the link members e.

Having fully described my invention, whatl claim as new and desire to secure by Letters Patent, is

1. A hinge comprising two main plate members the backs of which are provided with oblong projections in the corresponding sides of which are formed main trans verse recesses which extend through said plate members and in the-top and bottom walls of which are formed transverse grooves, the back walls of said recesses which extend to the front faces of said plate members being also provided with supplemental recesses, oblong floating link members mounted transversely of the sides of said plate members in the main recesses and provided with end portions or projections through which are passed pins movable in said grooves, and L-shaped link members one end portion of which 15 pivoted to said floating link members centrally thereof and the other end portions are pivoted in said supplemental recesses.

2. A hinge comprising two similar main plate members, the backs of which are provided with oblong projecting-body portions, said body portions being provided in the corresponding sides thereof with main transverse recesses which extend through said plate'members and the top and bottom walls of which are provided with grooves which range transversely of said plate members and at right angles thereto'and which open backwardly through said body portions, but do not extend entirely through said plate members, the back walls of said recesses being also provided in their front edges with supplemental transverse recesses in planes at right angles to the planes of said grooves, oblong floating link members placed transversely of said plate members and in said main recesses and the ends of which are connected by pins which pass therethrough and the ends of which are movable in said grooves. and L-shaped link members one end portion of which is pivoted to said floating link members centrally thereof and the other end portions of which are pivoted in said supplemental recesses.

3. A hinge comprising two main parts, floating links slidably connected with said parts and other links pivoted to said parts and to said floating links.

4. A hinge comprising two main parts, floating links slidably connected with said parts and provided at their ends with pins which are passed therethrough and the ends of which are movable in grooves formed in said parts, and other'links pivoted to said floating links and to said main parts. i

5. A hinge comprising main attaching members, floating members slidably connected with said main attaching members, and devices connected centrally with said floating members and with said attachin j C. E. MULREANY, FRANK G. Ar LEE.
